PICK-STICK. CHECK.

Specification of Letters Patent.

Patented Nov. 25, 1919.

Application filed. April 2, 1919. Serial No. 287,043.

To all whom it may "concern:

Be it known that we, JOHNVW. HERBERT and JAMES A. ANDREWS, citizens of the United States, residing at Biddeford, in the county of York and State of Maine, have invented a new and useful Improvement in Pick-Stick Checks, of which the following is a specification.

This invention relates to certain new and useful improvements in a pick stick check and its primary object is to provide an improved support and guide for the check strap in which the latter is given an intermittent feed action by the pick stick, the feed or movement of the strap being in a single direction.

The invention also resides in improved means for supporting the belt against sagging which lengthens the life of the belt or strap as well as holds'the same in a position in which it operates most eificiently.

Further, the invention residesin the features of construction and the arrangements and combinations of parts hereinafter described and claimed, reference being bad to the accompanying drawings wherein- Figure 1 is a side elevation of the pick stick check constructed in accordance with the present invention.

Fig. 2 is a bottom plan view of the same.

Fig. 3 is a side elevation of the check structure as viewed from the opposite side thereof.

Fig. 4 is same on line 44 of Fig. 1.

Referring more in detail to the drawings, the lay 1 guides the pick stick 2 in its oscillatory movements which are checked and cushioned by means of the check strap 3 having a thickened upper portion A to reinforce the same against the action of the.

stick. The belt or strap is guided beneath the lay by a pair of frames constructed and mounted in the following manner.

The frame depicted in Fig. 1 comprises a base 5 bolted to the outside of the lay and provided with a pair of downwardly extending guide fingers 6 spaced longitudinally of the lay, their active or guiding faces "being convexed. A third guide finger 7 operates on the opposite side, or the inner face of the strap, and between the guide fingers 6, the same having an outturned foot 8 to guard against accidental dislodgement of the strap, as by slipping off the ends of a transverse section through the the fingers, and in its upper portion the finger 7 is formed with a cut-out or groove 9 to receive the thickened portion 4;. This third finger has a lateral bracket extension 10 on its upper end and the outer end of this bracket extension is offset to underlie a flange 11 on the base 5. The bracket extension has a sliding tongue and groove fit with the flange 11 and both are slotted to receive the shank of an adjustable securing bolt 12. I

The companion frame depicted more clearly in Figs. 3 and i, comprises a bracket 13 bolted to the opposite side of the lay 1 and supporting a depending substantially U- shaped belt guide 14 opening outwardly. The inner wall of this guide is formed with a groove 15 to receive the edge enlargement of the belt, and the upper and lower sides of the Uastructure' are formed with registering apertures through which a bolt 16 is inserted.

A cam 17 is pivoted on the bolt 16 to swing 7 toward and from the inner wall of the guide to clamp and release the interposed belt. A spring 18 is coiled around the bolt and has one terminal seating between two ribs 19 on the "cam and its opposite terminal engaging over a projection 20 carried by the lower side of the guide whereby the cam will become operative to clamp the belt against movement in one direction although it will give or yield outwardly to permit free movement in a reverse direction. The nut 21 of belt 16 is seated in an opening 22 cut out in bracket 13 so as to be held against loosening.

Extending from the opposite ends of the lower side of guide 1 1 are the horn-like projections 23 which underlie the belt and support the same from sagging whereby the belt or strap is sustained in a position to operate most effectively and efficiently. It'will be noted that the guide and these horn projections extend at an inclination to the path of travel of the pick stick and in the direction of travel of the belt. The latter is therefore supported against sagging for the greater portion of its length as is most clearly shown in Fig. 2.

The bolts 24 which attach the brackets 5 and 18 to the opposite sides of the lay, have their nuts 25 disposed within slots or recesses 26 opening through the bottom of the lay, which arrangement leaves the walls of the guiding slot of the lay uninterrupted and provides a housing for the nuts.

In operation, when the pick stick strikes but as the stick strikes the opposite end of the loop the cam becomes operative to se-' curely hold the strap against retro-grade movement through the U-guide' The strap is thus given an intermittent movement to continually present a new striking surface to the stick. The bracket 13 may be adjusted by reason of the slot 27 through which the bolt 24 passes, and the guide finger 7 may also be adjusted as the circumstances and conditions require.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is- 1. A pick stick check comprising a bracket having spaced depending guiding fingers and an outwardly'extending flange over the upper end of one finger, a third guiding finger interposed between the spaced fingers to engage the check strap on the opposite face, said third finger having a lateral bracket eX- tension offset from its upper end underlying the flange, and means adjustably connecting the bracketv extension to the flange.

2. A pick stick check comprising a check strap, a guide frame therefor having a U- shaped guide opening laterally, the lower side only of the guides being ektended in op- I posite directions whereby to constitute a flat support for the lower edge of the strap.

3. A pick stick check. comprising a check strap, a guide frame therefor havlnga broad flat horn extension underlying and 'supporting the strap for both lateral and lengthwise 5. In combination with the lay of a loom,

a check strap having an internal enlargement at its upper portion, and'guide frameson 0p positesides of the lay through which the strap passes, theinner guide faces of said frames being formed with grooves to receive the strap enlargement.

In testimony whereof we have signed our names to this specification in theipresence of two subscribing witnesses. Y
